Installation with safety systems
SSV
The SSV must have a dedicated sensing
line, whose point of sensing provides a
representative pressure. An isolating valve
on the sensing line is not permitted.
Monitor
The RB4000 regulator can be used as
monitor regulator. It sensing shall be piped
downstream from the active regulator, as
shown in the Fig 5
